What the author says it does
🚀 The Ultimate Image Optimization Plugin for WordPress
⚡ Speed up your website with automatic image compression, WebP and AVIF conversion, and bulk optimization. Optimize images and PDFs, resize large uploads, and reduce file sizes with minimal setup.
Smaller images help your pages load faster, giving visitors a smoother experience, supporting your website’s SEO, and helping turn more visits into conversions.
🆕 New! AI image renaming and assistant support
- AI-generated, SEO-friendly filenames – Say goodbye to generic filenames like “IMG00931.JPG”. Automatically generate descriptive, SEO-friendly filenames for new uploads or existing images not yet used in published content.
- Manual file renaming – Rename images directly from the Media Library, including their thumbnails, WebP/AVIF versions, and backups.
- Multisite network settings – Manage ShortPixel settings across your network from one place.
- WPML and WP Offload Media compatibility – File renaming supports WPML Media Translation and WP Offload Media, including images stored only in the cloud.
- AI assistants and MCP support – Connected AI assistants can optimize and restore images, run bulk jobs, generate or undo AI Image SEO data, check statistics and credits, and adjust settings through the WordPress Abilities API and WordPress MCP Adapter. Actions follow your WordPress user’s permissions. Read more.

Questions the author answers
How does ShortPixel compare to other image optimisation plugins (e.g Smush, Imagify, TinyPNG, Kraken, EWWW, Optimole)?
ShortPixel consistently has better compression rates along with more features, backup support and has very affordable one-time or monthly plans.
Here are a couple of independent reviews:
AuthorityHacker – “ShortPixel is our tool of choice, simply because it’s pretty much automated – we just let it do its thing.” (read full review)
Can I use the same API Key on multiple web sites?
Yes, you can.
As long as you have available credits, you can use a single API Key on as many websites as you wish!
What plan is better for me? What do you recommend?
Everyone has different needs, but generally, we recommend getting a One-Time plan to optimize your whole Media Library and then get a Monthly plan to optimize your future uploads. To learn more, have a look at this comparison
How many thumbnails do I have, and which plan should I choose?
To know how many thumbnails you have, just install the plugin and go to Media > Bulk ShortPixel. The plugin will tell you how many thumbnails you’ve got. Based on this, have a look at our plans
Can I upgrade/downgrade easily my plan?
Of course. You can upgrade or downgrade your plans in a couple of clicks from your account on shortpixel.com.
Can I test/use the plugin for free?
Yes, you can.
We offer 100 free image optimization credits each month. Exceeding the monthly free quota will pause the optimization process till the quota is reset or extended by buying one of our plans.

Where this page's numbers come from
Read from the WordPress.org plugin API on , when WordPress 7.1.4 was the current release. WordPress.org rounds active installs into buckets. These are the directory's figures, not my verdict, and I haven't tested this plugin.
